Abstract: Several network node addresses are assigned to at least one link in a network node of a packet switching communications network that contains several network nodes and several links leading to other network nodes. The data-packet traffic that arrives at the network node is divided between the number of configured network node addresses that lead to a target network node and is transmitted.

Abstract: The invention relates to a method and a device for adapting label-switched paths, in particular MPLS paths, in packet-oriented networks which comprise routers. At least some of the routers exchange information with adjacent routers, by means of a protocol, about the status of the network, in particular about load shifts, availability changes and bandwidths, in order to recognise possible bottlenecks or improvements and, in the case of adjacent bottlenecks, locally altering paths which run through said bottlenecks, by means of partial replacement paths such that said bottlenecks are by-passed and in the case of adjacent improvements, the paths which run around said improvements are altered such as to retain said improvements in the path.

Abstract: The invention relates to a method for establishing a distribution compartment in a packet-switched network. A classification of the network nodes is carried out according to output nodes of the network during which the class of a node is determined according to the minimum number of hops between the network nodes and the output nodes. Based on the classification, distribution compartments for flows can be established as to provide a freedom from loops and to enable a flexible reaction to malfunctions.

Abstract: The invention relates to a device and a method for transmitting a plurality of packet-oriented signals within networks (18, 19), especially for switching and routing in networks (18, 19). Said device comprises a plurality of port units (14) comprising at least one port (15), said ports being able to be connected to the networks; a transmission unit (16) which preferably has the function of a crossbar switch; and at least one first protocol unit (12) which analyses at least part of the signals and determines their destination. The inventive device comprises a plurality of other protocol units (17) which are directly associated with the port units (14) and which classify the signals according to their transmission protocol, in order to independently take on the protocol processing for part of the packets, and to transfer the protocol processing for the other part to the first protocol unit.

Abstract: The invention relates to a circuit arrangement for data stream distribution with conflict resolution, whereby data streams are transmitted bi-directionally, such that first data stream connection units (104a-104n) and second data stream connection units (105a-105m) serve as both input and output connections. A distribution unit (100), essentially comprises a matrix switching unit (101), first intermediate buffer units (106a-106n) and second intermediate buffer units (107a-107m). Information is firstly evaluated in the cell head, which, together with information on the availability of intermediate buffer units, determine when a present data stream cell may be transmitted to a relevant output connection unit.
